Application filed itovember My invention pertains to an inking surface cleansing appliance and more particularly to mechanism for cleaning the surfaces on which ink is spread 1n printing presses, which 5 is called in the art a wash-up procedure.

The disclosures herein present 'a' development of the underlying principles shown, described and claimed in my co-pending application filed August 2, 1926, Serial No. 126,491

.0 and constitute in certain respects improvements over the disclosures of that earlier application.

The object of my invention is primarily. to

facilitate the wash-up of a printing press -.5 preparatory to rpnning thereon a difierent job, frequentlyusing a different color of ink, and also to perform'this operation in very much less tinae. j .According to my present disclosures a receptacle is provided into which the dislodged ink will be drawn after being first thinned 'by the application of'a diluting vehicle, benzene for'instance. A yielding wiper is employed which will .p'ermitof' printing even while the wiper-is in contact with an carrying surf ce or until the-ink be diluted as previousl suggested. This. possibility presents the advantage of permitting "the wash-up? of one-half of the press at a time, while the friction still existing on the other half continues to-transfer power from one roller to another, it being preferable not to have any inking roller stall, -i. e.,' s'lide, which would occasiona back wash and spillingdf a benzene over other parts of the' press.

' After use of my appliance. the inking surfaces are left absolutely clean and dry so that the press can again be inked-up immediately after the wash-up because even the pores of the rollers have been. cleansed and no film of benzene remains to interfere with the depositing of the new ink.

It is to be realized that the scope of my invention 'comprehends many equivalent-constructions and some changes in practicing the method. The showing of the drawings and the particular description are merely a specific exemplification. 1 i

Adverting to the drawings: 5Q Figure I is aside elevation of the essential 'elementsof a printing press showing my appliance attached thereto."

Figure III is a plan view of one inking roller and of the wiping structure.

Figure IV is an enlarged cross-sectional view on line IVIV of Figure III.

Figure V is a still further enlarged fragmentary view on line V-V of Figure III.

Figure V1 is a fragmentary view of a hinge element as viewed jon line VI- --VI of F igure II.

Figure VII is a bottom view of the washup attachment observed in the direction of the arrow VII in Figure II.

A bed 1 of a press carries up right standards 2, on which are rotatably mounted a series of inking rollers 3, each in fr ic'tional engagement with a plurality of others. One of the rollers, 3 is to be driven by a gear 4 as appears in Figure III and in .a manner common to the art. Projecting from the standards 2, at points somewhat below the axis of the driven roller 3, are brackets 5. The upper surface of. these brackets are designed in conjunctionwith bearing caps 6, detachably secured .by means of screws 7, to provide bearing's for a pair of studs 8, one of which has a screw threaded extremity 8, and which studs project from opposite ends of a cleansing structure support 9, as appears in Figure VII. I As illustrated in Figure V, a series of screws 10, which are passed downwardly through'the support 9, in a row extending crosswise of'the press, support a pipe 11 with which isassociated a di'agon ally upward plate 12-f0rming an inlet passage 13 in conjunction 'with;a portion'of the lower side of the support 9 andin conjunction further with a beveled upper end 9"- of the latter. The pipe 11 is Suppl id with a series of equi-spaced openings 14: communicating with the inlet passage 13, as likewise appears in Figure V. The ends of the pipe 11 are closed by caps 11 (see Figure VII) and the middle of the pipe '11 commun eat-es with a pipe 15 the other end of which is clamped at 16- to one end .of a flexible tube 17 (see Figures I and III). The tube 17 is connected with a receptacle 18, as is also anothertube 19,.having a valve connection at 20 iio is held in place by anut 30. The element 28' is hingedat 31 to an arm 32 which carries a handle 33. The purpose of the hinge structure is to permit of effecting slight turning adjustments of the wiper carrying structurein a direction to increase the pressure of the wiper 27 against the roller 3. For the purpose of effecting and maintaining such turning adjustments, one of the brackets 5 carries an ear 34 with which a set screw 35 is in threaded connection and positioned to engage oneside of the lower end of the arm 32. Should it be desired to withdraw the wiping :structure from the roller 3, the handle 33 may be grasped and the arm 32 forced beyond the end of the screw 35 (which is possible be- .cause of the yielding of the unclamped portion of the wiper'27) and then the arm 32 may be swung upward on its hinge to clear the screw 35, whereupon the entire wiping structure may be swung to its dotted-line position,

as shown in Figure II. In such position, the

arm 32 may be placed in a fork 36 which is fixed to the bracket 5 and be there locked by" the insertion of a pin 37 through registering holes in the fork36.

The operation of my appliance is as follows: I I v After the printing press has been supplied with its ink preparatory to running a job, the

wiping structure may either be caused to assume its dotted-line position, indlcated in Figure II, or even vin its full line position because practice has demonstrated that without dilution of the viscidink the wiper 27 will not dislodge the ink coating.- When it is desired to cleanse the inking surfaces, the wiper .27 should, of course, contact the periphery of the roller 3 with that degree of pressure which experience will have taught the conditions to prescribe, after which benzene or some other suitable diluting vehicle is supplied to say, one-half of the crosswise extent of the wiper 27 andthe motor 23 set in motion with the valve 20 open. After the ink on one-half of the various rollers has been progressively rei moved and withdrawn through the inlet 13, orifices 14 coniiection's to the receptacle 18; the other half maybe similarly dried and cleansed.

What I believe to embrace patentable novelty and therefore claim, is:

In a printing press, the combination of a bed, a type form, a plurality of inkingrollers in peripheral contact each with another and adapted frictionally to transfer rotational movement, a structure carried by said bed and including a duct having an inlet opposed to one of said rollers, an obliquely presented wiper carried by said structure directly above saidinlet and yieldingly contacting a receding upper semi-cylindrical portion of the periphery of the same one of said rollers with reference to the direction of presentation of said wiper, the arrangement being such that no retardation of the rotational movement of the particular roller occurs while the wiper dislodges ink during a partial wash-up of the press involving the application of a diluting 30 fluid to a portion of the line of contact between said roller and wiper and a suction appliance connected with the other end of said duct.
